Why Choose the Carlo Gavazzi RK2A60D75C Solid State Relay?
The Carlo Gavazzi RK2A60D75C is a robust two-pole solid state relay (SSR) designed for reliable switching of two-phase AC loads in industrial automation, heating and electrical control applications. As part of the Carlo Gavazzi RK series, it uses zero-cross switching technology to help reduce electrical transients and electromagnetic interference when switching AC loads.
This panel-mounted solid state relay provides semiconductor switching without the mechanical contacts associated with conventional electromechanical relays. Its two-pole configuration provides switching across two AC load poles, while the built-in overvoltage protection helps protect the semiconductor switching stage in demanding industrial environments.
With a rated current of 75 A per pole and an operating voltage range of 42–660 V AC, the RK2A60D75C is designed for high-current industrial loads. The relay uses a 4–32 V DC control input, zero-cross switching and a 2.54 mm pitch connector-pin control termination. Its high 9800 A²s I²t rating provides enhanced short-duration overcurrent withstand capability when used with a suitable heatsink.
